As the pursuit of healthy aging becomes more mainstream, many are turning to supplements to support not just lifespan but healthspan\u2014the years we spend feeling vibrant and resilient. Neuroscientist Dr. Kay Linker<\/a>, PhD, explains that certain compounds show promising evidence in supporting cellular health, brain function, and overall longevity<\/a>. Here are five supplements she highlights for those looking to age well.<\/p>\n

1. Spermidine<\/p>\n

Spermidine is a naturally occurring polyamine that stimulates autophagy, the body\u2019s way of clearing out damaged cells and making room for new, healthy ones. \u201cSpermidine supplementation extends lifespan across multiple species, including yeast, flies, worms, and mice,\u201d Dr. Linker notes. Human research also supports its benefits: the Bruneck Study tracked participants for 20 years and found that higher dietary spermidine intake was associated with lower all-cause mortality and fewer cardiovascular-related deaths<\/a>. It\u2019s basically “cellular spring cleaning.”<\/p>\n

2. Ca-AKG<\/p>\n

Calcium alpha-ketoglutarate (Ca-AKG) plays a critical role in the Krebs cycle, supporting cellular metabolism and even epigenetic regulation. Animal studies show it can extend both lifespan and healthspan, while early human data are encouraging. In the TAME-K study, participants taking Ca-AKG for seven months experienced an average reduction in biological age of roughly eight years. It\u2019s like giving your cells a metabolic tune-up.<\/p>\n

3. Urolithin A<\/p>\n

Urolithin A is produced by gut bacteria<\/a> when we consume foods like pomegranates, berries, and certain nuts, Linker notes. Its main function? Stimulating mitophagy, the process of clearing out old mitochondria and generating new, healthy ones. Preclinical studies demonstrate lifespan extension and improved muscle function, and a 2022 human trial showed four months of supplementation improved muscle endurance and mitochondrial biomarkers in middle-aged adults, she adds. Strong mitochondria equal strong energy and vitality!<\/p>\n

4. NAC<\/p>\n

N-acetylcysteine (NAC) is a precursor to glutathione, the body\u2019s primary antioxidant, which naturally declines with age. She states that while animal studies have shown mixed results regarding lifespan extension, NAC is protective against neurodegeneration, cardiovascular disease, and immune decline. It helps combat oxidative stress<\/a> and cellular damage, which are major contributors to aging.<\/p>\n

5. Astaxanthin<\/p>\n

Astaxanthin is a carotenoid found in marine organisms, 100 times more potent than CoQ10 in cellular antioxidant assays, she reveals. While no direct lifespan studies exist, human trials demonstrate improvements in skin health, eye health, cardiovascular function, and cognitive performance. It\u2019s a powerful supplement<\/a> for anyone looking to reduce inflammation and oxidative stress while supporting beauty and brain function as they age.<\/p>\n

Bottom Line<\/p>\n

Dr. Kay Linker emphasizes that these supplements aren\u2019t miracle pills\u2014they work best when combined with a healthy diet, regular exercise, and proper sleep. \u201cThese compounds target cellular health, inflammation, and oxidative stress, which are the real drivers of aging. Supporting these systems can help you age gracefully and maintain vitality,\u201d she concludes.<\/p>\n","protected":false},"excerpt":{"rendered":"As the pursuit of healthy aging becomes more mainstream, many are turning to supplements to support not just…\n","protected":false},"author":2,"featured_media":403346,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[36],"tags":[49,48,84,395],"class_list":{"0":"post-403345","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-nutrition","8":"tag-ca","9":"tag-canada","10":"tag-health","11":"tag-nutrition"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/403345","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=403345"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/403345\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/403346"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=403345"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=403345"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=403345"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
